53) A buffer solution contains carbonic acid (H CO) and sodium bi carbonate (NaHCO), each at a concentration of 0.100 M. The relevant equilibrium is shown below. What is H:COs(ag)+ HOo (a)+HCOs (ag) K.-4.5x 10 54) At 40 C, the pH of water is 6.77, what is lon-Prodact Constant for Water, Kw.at 40°C 55) If a solution of acetic acid has a pH-2.74 and a pK474, wh in the solution? Show your calculations is the ratio of (CH Co/ICOH) 56)...
The following primary standards can be used for the standardization of bases except. a. Benzoic acid b. Oxalic acid c. CaCO3 d. KHP A solution that may contain NaOH, Na 2CO3, and NaHCO3, alone or in compatible combination was titrated with 0.1200 M HCl. The volume of the acid required to reach the phenolphthalein endpoint was 25.67 mL while 38.13 mL to reach the methyl red endpoint. What are the components of the mixture? a. Na2CO3 only b. NaOH only...
just need help with questions 3. a & b always rate!!! Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
